Climate change, global warming and the impact of C02 on the planet is the most complicated issue of our times.

That's why Ian Cooper has come up with a simple way to illustrate it.

The engineer, science teacher and sometime author has put together a chamber in his backyard that goes a long way to explain how various emissions affect the atmosphere.

"I conceived this very simple experiment. One side being a controlled situation with the standard atmospheric conditions, the other beginning with C02 injection. Immediately we got a quite a divergence in the temperature gradients," Ian says.

"The conclusion that I'm trying to draw from this is; if we keep injecting so much carbon dioxide into our atmosphere it is inevitable that the atmospheric temperature will rise."

Despite the stark results, Ian views the future with optimism.

"Our aim is to take this to school, because they're our big hope. The situation can be turned into something exciting. There is enormous potential and opportunity for new industries and through that new employment."
